Energy Resources

Env. Science Energy Resources Vocabulary

Fossil Fuel Fuel consisting of the remains of organisms preserved in rocks in the earth's crust with high carbon and hydrogen content
Coal A carbonaceous rock formed from buried plants in ancient forests or swamps
Peat Partially carbonized vegetable matter saturated with water; can be used as a fuel when dried
Brown Coal Lignite; The first type of coal formed and has the least amount of energy
Sub-bituminous Coal and Bituminous Coal Dark black coal that are most important for energy production for direct heating and electricty
Anthracite Coal Dark gray; have a high energy content
Petroleum A dark oil consisting mainly of hydrocarbons
Maturation The burial and chemical transformation process that leads to formation of petroleum
Strip Mining The mining of ore or coal from an open mine
Acid Mine Drainage Any pollutional discharge emanating from a mining operation
Energy Efficiency The amount of energy consumed per unit of productive output
Synfuels Hydrocarbon resources other than oil, natural gas, and coal; also called unconventional hydrocarbons.
Tar Sands Deposits of dense, thick, asphaltlike oil that cannot be pumped easily
Kerogen Wax like compound that may be formed if organic material is buried; also called oil shales
Gas Hydrates Deposits of methane that are frozen into ice in permafrost and in seafloor sediments
Fluidized Bed Combustion Coal is burned more efficiently at a lower temperature than in a conventional power plant.
Coal liquification Turning solid coal into liquid fuel similar to oil
Green Power Electricity that is generated by a nonpolluting technology
Fission Inducing a heavy atom to split into lighter atoms
Nuclear Reactor A device in which nuclear chain reactions are initiated, controlled, and sustained at a steady rate
Fuel Rods A long, slender tube that holds the fuel pellets
Nuclear Waste Highly radioactive by-products of nuclear fission
Half-life The amount of time it takes for the level of radioactivity in a material to be decayed by half.
Fusion Two atomic nuclei come together to produce energy
Passive Solar Heating Direct solar energy used for applications such as home and water heating
Active Solar Heating Solar energy is collected, usually by solar panels on a rooftop, and the heat is stored and distributed by fans or pumps.
Photovoltaic Cells Thin wafers or films that are treated chemically so they absorb solar energy, emitting a stream of electrons in response.
Electrolysis Splitting water into its component parts
Fuel Cells An electrochemical energy conversion device that produces electricity from external supplies of fuel.
Anode The negatively charged pole of a fuel cell
Cathode The positively charged pole of a fuel cell
Wind turbines A machine that captures the energy of the wind and transfers the motion to a generator shaft
Wind Farm A group of wind turbines in the same location used for production of electric power
Biomass Energy Energy derived from Earth's plant life
Biogas Methane gas released from animal waste that is used for energy
Ethanol A form of alcohol made from fermented sugars found in corn and other crops that is added to conventional gasoline
Biodiesel A form of fuel that is made from vegetable oil
Hydroelectric Power Energy generated from a stream of water flowing downhill...gravitational energy.
